1. I will go with Outlook as it seems the Mail app is till buggy according to my test emails. The messages were sent through, but I hear no notifications sounds or notifications at all, except on the Mail app icon (Badges). I left all notifications for the Mail app as default (untouched) and they seemed fine.
2. Outlook on a Windows computer? Use our manual for Outlook on Windows. Follow these steps in Outlook for Mac 2016/2011: Right-click on the e-mail whose header you want to view and choose 'View Source' in the menu. The top part of the source is the mail header (see image).
3. Free with Outlook for iOS Connect. Get things done on the go with Outlook mobile. Work efficiently with email, calendar, contacts, tasks, and more—together in one place. Office integration lets you share. May 25, 2020 In this post, we shall compare Outlook Mail for Mac to the default Apple Mail app.

Even if you don't work on a computer during the day, you probably sit down in front of it to check your inbox at the end of the day. If the Mail app that comes with your Mac doesn't provide the features you need, you're in luck. There are dozens of great email apps in the Mac App Store. I've tested many of them and these are my favorites.

Symptoms

When synchronization issues occur in Microsoft Outlook 2013 or Outlook 2010, you may experience one or more of the following symptoms.

• Symptom 1

  You see differences or mismatches between the messages that you receive in Outlook compared to those that you receive in Outlook Web App (OWA).

• Symptom 2

  You experience an issue in Outlook, but that issue doesn't occur when cached mode is disabled.

• Symptom 3

  You occasionally receive error messages when you synchronize your Offline Folder OST file (.ost) in Outlook with your mailbox on a server that's running Exchange Server.

• Symptom 4

  You notice that some items such as email messages, appointments, contacts, tasks, journal entries, and notes are missing from your OST file or from your mailbox after you synchronize your OST file and your mailbox.

Cause

The reason for these symptoms and other problems in synchronizing might be a corrupted OST file.

Resolution

If there's an issue with a specific folder, you can resynchronize the folder in Outlook 2013 or Outlook 2010. Follow these steps:

1. Right-click the folder, and then click Properties.
2. Click Clear Offline Items > OK.
3. On the Outlook ribbon, click the Send/Receive tab.
4. Click Update Folder.

If this method doesn't resolve the issue, we recommend that you rebuild the OST file. That is, delete the OST file, and then let Outlook create a new OST file and download the information again from Exchange Server. To do this, follow these steps.

How to rebuild the OST file

1. Locate the following folder in Windows 8, Windows 7, or Windows Vista:

   C:Users AppDataLocalMicrosoftOutlook

2. If the folder isn't displayed, unhide the folder:

   • On the View menu, click Options.
   • Click the View tab, select the Show hidden files and folders check box, and then clear the Hide extensions for known file types check box. Click OK.

3. Rename any OST files by changing the OST file extension to .old. If the OST file name extensions aren't displayed, make sure that you clear the Hide extensions for known file types check box, as described in step 2.

   Note

   If you receive a File is in use error message, press Ctrl+Alt+Delete, and then click Task Manager. Click the Processes tab, and verify that Outlook.exe and Winword.exe aren't displayed in the list of processes. If these processes appear in the list, select each file, and then click End Process.

4. After you rename the OST file, start Outlook. You'll receive a Preparing for first use message. Wait for the mailbox to synchronize. The time that this process takes will vary, depending on the size of the mailbox.

5. After the mailbox is synchronized, test to see whether the issue still occurs. If it still occurs, the OST file isn't the cause of the issue.

Important

There's an exception to this conclusion: when you have local data that's not present on the server. In that situation, we recommend that you follow these steps:

1. Export the data to an Outlook Data File (.pst), and then delete the OST file.
2. Let the server data download again, and then import the .pst file data by using the Do not import duplicates option. To access this option, click File, and then click the Open & Export option in Outlook 2013 or the Open option in Outlook 2010.

Email Compatibility

Not all email systems are compatible with Duo. You'll find a list of supported email clients below.

Make sure that your email client is supported before you enroll in MFA/Duo to avoid service interruption. The Duo Help Center (https://help.duo.com) is also available for additional support information.

*The one that came with your device

NOTE: Thunderbird, Mac Mail, and the Android native mail app are currently compatible with Duo and DavisMail. But in the future, as we continue to strengthen the security of our email platforms, some older email clients will no longer work with Duo and DavisMail. We will inform the community about all changes that will affect their ability to access their email, and we will assist them in upgrading their email client to the most secure, supported versions.

Outlook Mail For Mac

Microsoft Mail App For Mac

Can I still use Mac Mail? Thunderbird? My native smartphone mail app?

Mac Mail, Thunderbird, and the Android native mail app do not yet support Modern Authentication which is required for Duo MFA. If your phone or computer uses one of those clients, you will need to install a new email client that supports Modern Authentication; good options include the Microsoft Outlook app for Android and iOS, and Microsoft Outlook for Mac and Windows. The 'OWA' (Outlook Web App) client for iOS and Android is not the same as the Microsoft Outlook app and does not work with Duo MFA. The iOS native mail app supports Modern Authentication and Duo in version 11 and later, however, after you enable Duo MFA for Office 365 on your iOS device, you will need to remove and re-add your email profile.
